The objective of the study was to evaluate myocardial stiffness in hypertensive patients by measuring the intrinsic velocity propagation (IVP) of the myocardial stretch and to explore the correlation between IVP and cardiac systolic and diastolic functions. Eighty-one hypertensive patients and 53 healthy patients were prospectively enrolled in this study. IVP was measured using high-frame rate tissue Doppler (350-450 frames per second). IVP was significantly higher in hypertensive patients than in the control group (1.53 +/- 0.39 m/s vs. 1.40 +/- 0.19 m/s, p = 0.031). In the hypertensive group, IVP was significantly higher in patients with electrocardiogram (ECG) strain than in those without ECG strain (1.63 +/- 0.46 m/s vs. 1.45 +/- 0.32 m/s, p = 0.047). Moreover, IVP exhibited a good correlation with interventricular septal thickness at end-diastole (r = 0.434, p < 0.001), left ventricular posterior wall thickness at end-diastole (r = 0.439, p < 0.001), E/A ratio (r = 0.245, p = 0.004) and global longitudinal systolic strain (r = 0.405, p < 0.001). IVP was significantly higher in hypertensive patients, which indicates elevated myocardial stiffness in this cohort of patients. This novel measurement exhibited great potential for use in clinical practice to assess myocardial stiffness in patients with hypertension non-invasively.
